MACHINE FOR CUTTING PATTERNS.

SPECIFOATION forming part of Letters Patent N o. 687,066, datedrNovember 19, 1901.

Application tiled April 1, 1901.

To a/ZZ whom it may concern,.-

Beit known that LCHARLES E. REED, a citizen of the United States,residing at Chicago,

county of Cook, State of Illinois, have inchines for Cutting Patterns,of which the following is a specification.

My invention relates particularly to that portion of the machine knownas the adjusting mechanism, by which the change of size is effected.y

In myreissued PatentNo. 1l,569,dated September 29, 1896, I havedescribed a machine to which my present invention is applicable, and itis designed to be an improvement upon the adjustment shown therein.

vThe object of my invention is to provide an adjustment which will beaccurate without lost motion and quickly and easily operated.

It consists of details hereinafter more fully described, andparticularly pointed Out'in the claims.

Figure l is a side elevation of a machine, showing my invention. Fig. 2is'a sectional view on lines 2 2, Fig. 4. Fig. 3 is a top plan view of aportion of a machine, showing my invention. Fig. 4 is a side elevationof the adjusting mechanism in detail. Fig. 5 is a plan view of a part ofFig. 4.

A represents the frame of the machine; B, the tracer; C, the cutter; D,the pattern; E, the pantagraphic frame; F, the rollers upon which thepantagraphic frame moves; G, the arm attached to the pantagraphic frameby which it is moved; H, the adjustment by which the movement ofthe armsis regulated; I, the guide the adj ustmeut moves in; J, the drivingmechanism; K, the grippinglever of the adjustment; L, the collar againstwhich it grips; M, the drum upon which the wirekis wound; N, the wire;O, the set-nut; P, the binding-post; Q, the shoe which slides intheguide I; R, the arbor about the adjustment; S, the stop on the arbor bywhich the swing of the gripping-lever is limited; T, the pivot theguideV swings u'pon,and U the bracket by which the pivot is supported.

The operation of my machine as a whole is the same as that described inthe beforementioned patent, the model pattern D at the tracer directingthe travel of the cutter in Serial No. 53,811.6. (No model.) f

the usual manner, and the change of size being eected in thel usualmanner by the movement of the adjustment; but my new adjustment differsfrom the old in essential features. The shoe S, Ahaving tapering sides,slides'in the guide 'Lpwhich has inclined faces to correspond. -Whilethe cutting is being done and it is necessary to hold it securely toprevent its longitudinal movement Ythe collar L and the 'wire N iswrapped one or two turns around it and has each end attached at or nearthe ends of the fiange I', which eX- tends along lthe guide I. Thegripping-lever is loosely mounted on the post P; but by pressing down onthe lever K it grips the collar L, and then by moving it in onedirection or the other the drum is turned and the wire is wound aroundit and the adjustment moved up or down the guide,'according to themovement of the lever. When the desired position is found, it isretained by turning up the setnut O, as above described, until thepattern is cut. Then it is released and set foranother size by means ot'the gripping-lever. The arm G, by which the pantag'raphic frame ismoved, is attached to the post P and moves with the adjustment. Theamount of movement of the adjusement is measured by the swing of thegripper, and this is regulated by adjusting the Vstop S to allow it alonger or shorter stroke, one stroke being ordinarily su'icient toeffect a single change of size in the pattern. The gripping-face of theygripper is roughened or milled and also the face of the collar which itgrips upon in order to prevent slippage. The guide is curved on the areof a circle and is pivoted in the bracket U.

What I claim, and desire to secure by Letters Patent, is

1. In a pattern-cutting machine, the herein-described adjustment,consisting of the combination of the movable amember Q, the

guide I in which saidmember Q moves, the drum M, attached to saidmovable member, the Wire N, Wrapped about said drum, the gripping-leverK, attached to said drum, and the arm G, carried by said movable member,all substantially as shown and described.

2. IIn a pattern-cutting machine the herein-described adjustment,consisting of the combination of the movable member Q, the guideI inwhich said member slides, the drum M, attached to said movable member,the Wire N, Wrapped about said drum, the collar L, attached to saiddrum, the gripping-lever K, which grips said collar, and the arm G,carried by said movable member, all substantially as shown anddescribed.

3. `In a pattern-cutting machine, the herein-described adjustment,consisting of the combination of the movable member Q, the guide I, inwhich said movable member moves, the drum M, attached to said movablemember, the Wire N, Wrapped about said drum, the gripping-lever Kattached to said drum, the set-nut O, by which said movable member isheld stationary, and the arm G, carried by said movable member, allsubstantially as shown and described.

4. In a pattern-cutting machine, the herecombination ot the shoe Q,having sloping' faces, the guide I, in which said shoe slides, havingcorresponding faces, the binding-post P, upon which said shoe ismounted, the drum M, loosely mounted upon said bindingpost, the Wire N,about said drum, the collar L, attached to said drum, the gripping-leverK, loosely mounted upon said binding-post,

the set-nut O, for binding said shoe to said guide, and the arm G,carried by said shoe, all substantially as shown and described.

CHARLES E. REED.
